What is the properties of cast iron?

What is the properties of cast iron?

Cast iron is harder, more brittle, and less malleable than wrought iron. It cannot be bent, stretched, or hammered into shape, since its weak tensile strength means that it will fracture before it bends or distorts. It does, however, feature good compression strength.

What is the tensile strength of cast iron?

Strength. The compressive strength of cast iron is 6.3 – 7.1 tonnes / sq. cm. It’s ultimate tensile strength is 1.26 – 1.57 tonnes / sq.

What is the maximum hardness of cast iron?

Brinell hardness of gray cast iron martensitic white cast iron (ASTM A532 Class 1 Type A) is approximately 600 MPa. Brinell hardness of malleable cast iron – ASTM A220 is approximately 250 MPa. Brinell hardness of ductile cast Iron – ASTM A536 – 60-40-18 is approximately 150 – 180 MPa.

What are the mechanical properties of white cast iron?

White cast iron has high compressive strength and retains good hardness and strength at a higher temperature. The presence of different carbides, depending on the alloy content, makes white cast irons extremely hard and abrasion resistant but very brittle.

What type of material is cast iron?

alloy
cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. It is made by reducing iron ore in a blast furnace.

What are the properties and application of different types of cast iron?

A few common mechanical properties for cast iron include:

• Hardness – material’s resistance to abrasion and indentation.
• Toughness – material’s ability to absorb energy.
• Ductility – material’s ability to deform without fracture.
• Elasticity – material’s ability to return to its original dimensions after it has been deformed.

What are the grades of cast iron?

Farmer’s Copper carries three main grades of casted iron products: V-2 (class 40) Gray Iron, V-3 (65-45-12) Ductile Iron, and V-4 (80-55-06) Ductile Iron. These products offer excellent compression strength and high vibration dampening capability.

What is the classification of cast iron?

Cast iron can be classified into grey cast iron, white cast iron, malleable cast iron and ductile cast iron, depending on its composition.

What are the 5 types of cast iron?

Various types of cast irons are produced using different heat treatment and processing techniques, including gray iron, white iron, malleable iron, ductile iron, and compacted graphite iron.

What is the volume of iron?

Iron has a density of 7.9 g/cm3. therefore, 1 cm3. of iron has a mass of 7.9 g. or 4 cm3. of iron has a mass of 7.9 x 4.0) g = 31.6 g. .

Which hardness test is used for cast iron?

Brinell hardness test It is a macro indentation test where a high load is used to obtain the measurement. Cast metals require macro hardness tests due to the course grain structure and the potential for an inhomogeneous material. Preparation of the metal surface for Brinell hardness testing is very important.

What is iron density?

7.874 g/cm³ (near room temperature)Iron / Density (near room temperature)

What is casting hardness?

Hardness is a natual characteristic of investment casting materials, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of investment castings. Different cast alloys will show different hardness results.

What is the Brinell hardness of cast iron?

Brinell hardness of gray cast iron (ASTM A48 Class 40) is approximately 235 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching.
